Secured to the cover is a hook,- ll, through which it may be lifted or moved from place by a suitable crane or other convenient means. I preferably provide tracks I I, extending through the opening 0 into the chamber A, although I leave a sufficient break or space in the track at its entrance to the chamber to allow of the proper manipulation of the cover or door 0, and I provide a car, B, adapted to contain slags and to be run into this chamber; or, if desirable, this car may be dispensed with, the tracks removed, and the slags allowed to How int-o or otherwise be placed in the chamber, and be removed or discharged therefrom by shoveling, or dumping, or other ways.

Vhile I have particularly described and shown one design of a steamgenerator, I do not wish to be confined to the use of this particular mechanical design, shape, or means of .operating or handling the parts, which may readily be variedas, for example, the openin g to the generating-ch amber may be smaller, and two or more openings substituted for the one, and the means of covering or closing it may be arranged in any convenient way, as by a hinged cover, or a cover run on a suitable track, with various means of securing it in place over the opening or passage.

As an example of another design of my generator, I refer to my application for United States Letters Patent for a process of generating steam by bringing water and slag in contact in a closed chamber, filed September 26, 1887, Serial No. 250,678. Y

Of course it will be understood that the proper water and steam pipes and valves are supplied to the steam-generating and steam receiving and washing chambers, where needed.

To wash or cleanse the steam generated in the chamber A and to equalize its temperature, I employ a chamber or drum, L, adapted to hold steam and containing a quantity of water, and connect it to the chamber A by the pipe K or other suitable steam-passages. This drum or chamber also serves as a steamstorage chamber. The steam generated in the chamber A passes through the pipe K and into and through the water in the chamber or drum L. It will be understood that the pipe K should connect with the chamber L below its water-line, thereby bringing all the steam in contact with and through the water.

In operating my steanngenerator I remove the cover or door 0, place a desired quantity of hot or molten slag or other similar material in the chamber A by means of the earl or other receptacle, when one is used, and replace the door, securing it with the screw E, and then in troduce water into the chamber in contact with the hot slag, by means of the pipe J, thereby converting it into steam and cooling the slag.

The steam passes through the pipe K to the chamber or vessel L and is cleansed, from which place it may be drawn for use. If desirable, there may be employed, separate storage and wash and cleansing chambers for the steam; or when the chamber L is not used the steam may be drawn for use directly "from the chamber A. \Vhen the slag has become so cooled as to no longer convert the water into steam, the door or cover 0 maybe opened, the slag removed, and hot slag put in its place. lVhen the chamber L or other steam-storage is used, the steam may be prevented from escaping through the chamber A while open by the proper use of the valve K in the pipe K. The chamber L may also be used as a steam-storage receptacle to afford a continuous supply for use, if desired. When desirable, two or more of these generatingchambers may be operated together and connected to the wash or storage chamber L, the chambers A being successively supplied and emptied of slag, whereby a more continuous supply of steam will be afforded to the storagechamber.

\Vhat I claim as new and desire to secure by Letters Patent, is

1. A slag steam-generator consisting of a chamber provided with suitable water-supply and steam-exh aust pipes, in combination with a vessel adapted to receive heated or molten materials, said vessel being constructed to be placed in said chamber, and means for closing the chambers, substantially as described.

2. A slag steam-generator consisting of a jacketed chamber provided with suitable water-supply and steanrexhaust pipes, in combination with a vessel. adapted to receive heated or molten materials, said vessel being constructed to be placed in said chamber, and means for closing the chambers, substantially as described.

3. A slag steam-generator consisting of a chamber provided with rails on the interior of the chamber and with suitable water-supply and steam-exhaust pipes, and means for closing the chamber, in combination with a wheeled vessel adapted to receive heated or molten materials and to be used in connection with the aforesaid chamber in the generation of steam, substantially as described.

4. The combination of a slag steanrgenerator having one or more steam-generating chambers and adapted to receive hot or molten materials and provided with suitable watersupply and steam-exhaust pipes or passages, and means for closing the said chambers, with a steam-receiving drum or chamber having a steam pipe or passage communicating with the steam generating chamber or chambers, whereby the steam may pass from the generating-chambers to the storage or receiving chamber, substantially as described.

5. The combination of a slag steam-generator having one or more chambers wherein steam is generated by bringing water into direct contact with hot or molten material, with IIO haust pipes or passages, a lining in said chamber to protect the shell or walling that forms the chamber and prevent it from being destroyed by the intense heat of the slag or the steam wi thin, substantially as described.
